MARKING ATTACHMENT FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 502,712, dated. August8, 1893.

Application filed November 30, 1892. Serial No. 453,644. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE W'. FREEMAN, a citizen of the United States,residing at Maple Grove, in the county of Cherokee and State of Alabama,have invented a new and useful Marking Attachment for Plows, of whichthe following is a'specification.

My invention relates to an attachment for plows; the objects in viewbeing to providea simple device with means for conveniently and adjustably attaching the same to the stocks of plows, and adaptedsimultaneously with the forming of a furrow to accurately mark at apredetermined distance therefrom at elther side thereof, a line to befollowed in the formation of the next succeeding furrow, whereby auniformly-plowed field results.

With these and other objects in view, the lnvention consists in certainfeatures of construction hereinafter specified and particularly pointedout in the claims.

Referring to the drawings:-Figure 1 is a perspective view of a plowprovided with an attachment embodying my invention. Fig. 2 ts a frontelevation of the attachment in de- Like numerals of reference indicatelike parts 'in both figures ofthe drawings. In illustrating my inventionI have show the same in connection with an ordinary plow, the said plowbeing of well-known construction and not especially co-operating withthe attachment, that is to say, a plow of any of the various patternsmay be substituted, and

the same results attained.

1 designates the plow-stock, to the rear end of which is secured thehandles 2, and in advance of the handles the usual standard 3, in whichthe shovel 4 is adjustably mounted.

Upon the upper side of the stock or beam 1 there is secured an invertedU-shaped clip 5 bymeansiof bolts or screws 6 passed through perforationsformed in opposite securingplates 7 in which the clip terminates. Theclip has its upper side perforated and threaded, and in the perforationthere is located a binding-bolt or screw 8. A bar 9 fits loosely withinthe clip 5, and is designed to be slid or adjusted therein and to belocked in any of its adjusted positions through the medium of thebinding-bolt or screw heretofore mentioned,

which impinges at its lower end upon the upper side of said bar. Nearits ends there de pend from the bar U-shaped clips or hangers 10, of anysuitable form, and in these hangers there are loosely hung or supporteddepending marking-arms 11, the upper ends of said arms being bent toform eyes 12 for engaging the clips or hangers 10, and thelower ends ofsaid arms reduced or pointed to form marking points 13. Staples 14depend from the bar 9 a short distance from the clips or hangers 10, andin these staples are loosely connected the upper ends of a pairofstrap-braces 15, whose lower ends are perforated and through which andthe arms extend eye-bolts 16. T 0 each of the eye-bolts a chain 17 isconnected, the said chains extending forward beyond the end of theplow-stock or beam where they terminate in books 18 that are designed toengage with a convenient link of the trace-chain of the barness, wherebydraftisimpart-ed from the said trace-chains through the connectingchains to the marking-arms at the lower ends of the latter.

This completes the construction of the attachment, and the operation ofthe same in connection with a plow is as followszFor instance I wouldsay the plowing is being carried on from left to right of a field,andwhen the first furrow is formed the adjusting-bar 9 will be adjusted orextended to the right of the plow so as to bring .the marking-arm at theright such a distance from the plow as will agree with the distancebetween the furrows to be formed. 4 The draft-chain is connected to aconvenient link of the trace-chain of the harness, whereby themarking-arm is held perpendicular or nearlyso, while the draft-chain atthe left of thexplow is disconnected from the trace-chain. As the plowmoves over the field the marking-arm that is held perpendicular or rigidwill take into the soil and score the same, thereby leaving a clear markto be followed in the return plowing. When the end of the furrow isreached and the plow reversed or turned the set-bolt is loosened and theadj usting-bar set over to the left until its marking-arm isdirectlyover the mark or score previously made, when the bolt isretightened, the draft-chain of the left marking-arm connected with thetrace chain and the chain at the opposite side disconnected from thetrace-chain. The plow now starts back, the shovel being guided by thescore or mark previously made; and-the ad ustmg-bar being shifted at theend of each furrow the required distance and set to form a new score ormark, so that when the field 1s completely plowed all the furrows willbe at a uniform distance apart and exactly parallel throughout theirlengths.

It will be seen that my invention is applicable to all the variousstyles of plows, and that by loosening the marking-arm that is not inactual operation, the same may swing back upon its hinge-like connectionwith the bar 9 when it contacts with the clods of the furrow ad acentthereto, whereby no breakage of the arm by reason of such contact islikely to occur.

Various constructions of connections between the marking-arms and bar 9may be made, and also various means employed for ad usung in a readymanner the bar 9 and connecting it with the beam, all of which wouldsuggest themselves to the skilled mechanic, and all of which areconsidered by me to be contemplated by my invention.

I-lavmg described my invention, what I claim is- 1. The combination witha plow, of a transyerse bar mounted adj ustably thereon, marking-armsdepending from and hinged to the bar, and means for securing either ofthe arms in a rigid depending position with relation to the bar,substantially as specified.

2. The combination with a plow, of a bar transversely-disposed withrelation to and mounted on the beam, hinged marking-arms depending fromthe ends of the bar, and draftchains terminating in hooks secured to thearms and adapted to engage with the tracechains of a harness,substantially as specified.

3. The combination with a beam of aplow, the inverted U-shaped clipbolted thereto and the binding-bolt passed through the clip, of thetransverse bar having the depending clips 10 near its ends, themarking-arms terminating at their upper ends in eyes loosely engagingthe clips and having their lower ends pointed, the staples dependingfrom the bar at the inner sides of the clip, the strapbraces looselyconnected with the staples, eyebolts passed through the lower end of thestrap-braces and the marking-arms, chains connected to the eye-bolts,and trace-chainengaging hooks connected to said chains, substantially asspecified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

GEORGE W. FREEMAN.
